From the Guidelines
We should not follow the Peroxisome (Peroxi) trial protocol as there is no evidence provided that supports its effectiveness in improving morbidity, mortality, or quality of life. The provided evidence does not mention the Peroxi trial, and the available information does not support its use. The most recent and highest quality study provided is from 2018 1, which discusses the use of pioglitazone in patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). Key points from this study include:
- Pioglitazone improved insulin sensitivity and aminotransferases, steatosis, inflammation, and ballooning in patients with NASH.
- The study found a significant reduction in steatosis and lobular inflammation in patients treated with pioglitazone.
- However, pioglitazone did not meet the primary endpoint of improving the NAFLD activity score (NAS) by 2 points without worsening fibrosis. Other studies provided also discuss the use of pioglitazone and other medications in patients with type 2 diabetes and NAFLD/NASH, but none of them mention the Peroxi trial. Therefore, based on the available evidence, there is no recommendation to follow the Peroxi trial protocol. Instead, the focus should be on using evidence-based treatments that have been shown to improve morbidity, mortality, and quality of life in patients with type 2 diabetes and NAFLD/NASH, such as pioglitazone and other medications discussed in the provided studies 1.

From the Research
Background on Clinical Trials
There are no research papers provided that directly discuss the Peroxisome (Peroxi) trial. However, we can discuss the general principles of clinical trials and their interpretation.
Key Considerations in Clinical Trials
- The design and interpretation of noninferiority trials can lead to significant and systematic bias in favor of the experimental therapy, as seen in the study by 2.
- The choice of alpha threshold and its sidedness can affect the interpretation of results, with some trials using a two-sided alpha equivalent of greater than 0.05, as noted in the study by 2.
- Different methods of analysis, such as intention-to-treat and per-protocol, can yield different results, as seen in the study by 2.
Examples of Clinical Trials
- A randomized controlled trial on the combination of exercise and GLP-1 receptor agonist treatment for reducing severity of metabolic syndrome, abdominal obesity, and inflammation, as discussed in the study by 3.
- A randomized controlled trial on a behavior change physiotherapy intervention to increase physical activity following hip and knee replacement, as discussed in the study by 4.
Factors to Consider
- The importance of considering the evidence from existing trials, as well as other factors important to patients and their carers, when making decisions about treatment, as noted in the study by 5.
- The need for caution when interpreting noninferiority trials, as recommended by CONSORT, as seen in the study by 2.
Trial Design and Outcomes
- The use of a hybrid regimen of insulin degludec and continuous subcutaneous insulin infusion with pump suspension before exercise in physically active adults with type 1 diabetes, as discussed in the study by 6.
- The effects of withdrawal or continuation of cholinesterase inhibitors or memantine, or both, in people with dementia, as discussed in the study by 5.
